As the Buddy Battles rage on, we continue to narrow down our field of favorite friends. (Alliteration!) This go-around is the battle of the crime fighters as flirtatious Morgan and Garcia from Criminal Minds go up against best bros Ryan and Esposito from Castle.

Which crime fighting crusaders will prevail? Will it be the detectives solving murders in New York City or the BAU members tracking down serial killers?

You know the drill, whoever wins this round will go on to do battle with the rest of the contenders to become BuddyTV's favorite dynamic duo.

UPDATE: Ryan and Espo narrowly beat Morgan and Garcia in a tight race!

It was a heart-pounding, tight race but Ryan and Esposito from Castle narrowly squeaked by Morgan and Garcia from Criminal Minds. It was a dead heat for awhile, but Ryan and Espo's bromance finally won the day.

Morgan and his baby girl Garcia put up a noble fight, including a lot of organizing on social media, which made this an exciting Buddy Battle to watch!

Last round, Ted and Marshall from How I Met Your Mother just barely squeaked past Shawn and Gus from Psych. Will it be another tight match, or will one pair prevail like Dean and Castiel in round one? Let's find out!

So let's take a look at the contestants!

Morgan and Garcia

Show: Criminal Minds

Why Vote For Them?

Baby Girl, you know you want to vote for Morgan and Garcia. Ok, enough talking like some sort of cross between Morgan and a Ryan Gosling meme. Let's get down to the straight facts: Morgan and Garcia are an awesome team. Not only are they flirtatious friends, they're also a crime solving unit without compare. Morgan can kick down doors and tackle unsubs, but Garcia can find out just about anything you can imagine using a few clicks of her mouse. Plus, nothing says it better than the episodes in which Garcia was shot and Morgan came to her rescue. Witty repartee, sexual tension, and finding serial killers: how do you beat that?

Ryan and Esposito

Show:Castle

Why Vote For Them?

If there were ever a pair that could give Morgan and Garcia a run for their money in the crime fighting buddies department, it's definitely Ryan and Esposito. While the two have played backup to Castle and Beckett on the show, they're always first in our hearts. These two get things done and their detective skills have helped solve more than a case or two during Castle's five seasons on the air. While Espo is the more outgoing playboy (in between his tumultuous relationships with Lanie), Ryan is the calmer and more stable of the two. This can make them an effective good cop-bad cop team. While the two have had their difference in the past (particularly at the start of this season) you can't keep these detective bros separated for long.

Remember, you have until 3pm PST/ 6pm EST tomorrow to fight for your favorites. You only get one vote, so make sure you make it count!
